IGNITER GAS AND GASOLENE ENGINES.

To all whom it may concern.-

Be it known that I, MAXIMILL AN G VoIe'rLANnnn, a citizen of the United ta'tes, residing at Harrison, in the county of Hamilton and Stateof Ohio, have invented certain new and ,useful Improvements in Igniters for Gas and Gasolene Engines, of which the following is a specification.

My invention relates to improvements in ignitcrs for gas and'gasolene eng nes.

One. of its ob ects 13 to P10V1(l6 8,1I1 1Pl6,

reliable and e'fiicient mechanism by means'of which a match may be gnited within the explosion chamber by the operator to secure an initial explosion to start the engine.

Another object is to provide mechanism by means of which the ignition of the match is, made certain, and by means of' which the match. may be readily and conveniently inserted and removed.

it further consists in certain details of form, combination, and 'arrangement, all of which will be more fully set forth in the description. of the accompanying drawings, in

which i Figure 1 is a side elevation of my improved mechanism in position for use, being shown mounted in the cylinder head, which with part of the mechanism is shown in section. Fig. 2 is an end view of the mechanism looking at the end Within the cylinder. a-section on line 1), o of,Fig. 1. Fig.' 4' is a perspective view of the inner end of the .match carrying plunger.

With larger sizes of gas and gasolene engines it is difficult to start the engines as is done with smaller engines by turning the flywheel by hand unt: an explosion occurs, and it is therefore desirable tostart such machines by explodin an initial charge or mixture of air and exp osive gas or vapor by hand operated mechanism, after which an electric 'igniter driven in conjunction with the en ine will ignite the succeeding charges .In t e. accompanying drawings A represents part of tlie wa l of the explosion chamber of the cylinder, preferably thecylinder head, which is preferably provided with an outwardly rejecting boss'A to receive the igniter. parts, a plug having-screw threaded en gagement with the c ,linder head A.

represents the ead of the plug which seats againstlthe cylinder head and is preferably ll'lllled on its exterior so as to be readily screwed in and unscrewed .by hand.

C represents a spiral groove in the inner projecting inwardly from the inner end of t e plug. The inner face d of finger-D is rovided with a roughened surface-"an .is

slightly eccentric to the axis of the plug as icate'd in Fi 2 and also tapers toward the axis of the p ug at its outer end as shown inFigl. w W

Mountedin the axial bore 1) of lug B is a plunger E having an offset e normsilly seating against a corresponding'oflset 'b? in the bore 6 These offsets serveto prevent the plum-- ger E being forced throughthe plug B by pressure from within the cylinder, and also form a close joint or valve to prevent the escape of gases from the cylinder at this point.

F represents a spring outside the cylinder head to retain the'plun er normally in the retracted position, and a knob or knurl pivotally connected to the outer end of pluh er E by means of setscrew g entering an 'annu ar recess 0 in the end of lunger E.

moval of t e match stem after it has been i nited. A pin L carried by the plunger. E s ides in the slot 0 andcauses the plunger E to partially rotate when pressed inward by means: of knurl G.'

In operation, when it is desired to start the engine, "the plug Bis first unscrewed and removed from the cylinder head, a match is inserted. in recess h, the excess match stem broken away, and the plug again screwed tightly into place in the cylinder head. The

ga s or gasolene valve is then opened and. the

engine turned or adjusted to take in an ex- The head .4, of the plosive charge and to the position ready for The knurl is then struck a sharp blow with the hand, which serves to ignite the match head,

at least a spark sull'i cient to explode the charge in the cylinder. The initial explosion produces a suflicient number of. revolutions of the engine to enable the electrical igniter to explode successive charges and the engine continues to run as long as desired.

The mechanism herein specified is capable of considerable modification without departing from the principle of my invention Having described my invention,.what I claim is 1. In a mechanism of thefcharacter in-,

dicated, a plug detachably connected to the cylinder to permit the adjustment of a match to place when detached, a segmental finger having a roughened surface, said finger being carried by said plug and projecting into the cylinder gases, a plunger mounted in said plug,

thereto, and provided at its inner end with when the means for holding'a match at an angle to, and

in position to contact with said roughened surface when the plunger is forcedinward.

2. In a mechanism'of the character indicated, a plug connected to the cylind er and adapted to be detached to adjust'a match to place, a finger carried by said plug having an inclined roughened surface in contact with the gases of the cylinder, a plunger-mounted In said plug adapted to move endwise rela tive thereto, and providedat its inner end.

with means for holding a match in position to contact with saidinclined roughened surface mounted on said plunger outside the plug to normally hold the plunger retracted and a knurl pivotally attached to the outer end of said plunger.

"3. In a mechanism of the character indicated, a-detachable plughaving threaded engagement with the cylinder, a finger pro; ectmg from said plug in contact with the,

cylinder gases and provided with a roughened.

adapted to move endwise relative plunger is forced inward, a spring erases surface, a plunger mounted in said plug adapted to move endwise relative thereto, and provided at its inner end with means for holding a match in position to contact with said rougheneds urface when the plunger is forced inward, and interengaging surfaces carried by said plug and plunger tov partially rotate 4., In -'a mechanism of the character indicated, a-plug connected to the cylinder and adapted to be detached to adjust a match to place, aprojecting finger having an inclined by Saidplug and in contact with the gases of the cylinder, a plunger mounted in said plug adaptedlto move endwise relative thereto, and provided at its inner end with means for holding a match in position to contact with said inclined roughened surface when the plunger is forced inward, and engaging oflsets carried by said plug and plunger to pre vent the plunger being forced outward by pressure within the cylinder. I

' 5. In a .mechanism of the character* indicated, a plug detaohably. connected to the cylinder, .a' "finger having an inclined roughpressure from within 'the cylinder, and the escape of gases between the plunger and plug.

In testimony whereof I have allixed my signature in presence of two witnesses.
